Moved fast around delicate ship's ornamentation (9)
I believe the answer is:
taffrails
'ship's ornamentation' is the definition.
Although both the answer and 'ornamentation' are nouns, they are not in the same form of the noun.
'moved fast around delicate' is the wordplay.
'moved' is an anagram indicator.
'around' is an insertion indicator.
'delicate' becomes 'frail' (synonyms).
'fast' with letters rearranged gives 'tafs'.
'tafs' enclosing 'frail' is 'TAFFRAILS'.
Can you help me to learn more?
(Other definitions for taffrails that I've seen before include "ship's bars" , "Members in ships" .)
